Ths use of just peak figures really is a factor. The THP configuration,
single JVM is the best configuration for numacore but this is only visible
for peak numbers of warehouses. For lower number of warehouses it regresses
but this is not reported by the specjbb benchmark and could have been
easily missed. It also mostly explains why I was seeing very different
figures to other testers.

Over the weekend I ran a few configurations that used a large number of
warehouses. The numacore and autonuma kernels are as before. The balancenuma
kernel is a reshuffled tree that moves the THP patches towards the end of the
series. It's functionally very similar to delaystart-v5r4 from the earlier
report. The differences are bug fixes from Hillf and accounting fixes.

In terms of testing, the big difference is the number of warehouses
tested. Here are the results.

Note for lower number of warehouses that numacore regresses and then
improves as the warehouses increase. The expected peak is 48 cores and
note how numacore gets a 43.14% improvement here, autonuma sees a 43.72%
gain and balancenuma sees a 64.98% gain.

This explains why there was a big difference in reported figures. I was
using Multiple JVMs as ordinarily one would expect one JVM per node and
to have each JVM bound to a node. Multiple JVMs and Single JVMs generate
very different results. Second, there are massive differences depending on
whether THP is enabled or disabled. Lastly, as we can see here, numacore
regresses for small number of warehouses which is what I initially saw
but does very well as the number of warehouses increases. specjbb reports
based on peak number of warehouses so if people were using just the specjbb
score or were only testing peak number of warehouses, they would see the
performance gains but miss the regressions.

Here you can see that numacore scales to a higher number of warehouses
and sees a 43.14% performance gain at the peak and a 36.63% gain on the
specjbb score. The peaks are great, just not the smaller number of
warehouses.

autonuma sees a 23.45% performance gain at the peak and a 42.74%
performance gain on the specjbb score.

balancenuma gets a 36.7% performance gain at the peak and a 53.32%
gain on the specjbb score.

balancenuma's is higher than I'd like.

Without THP, numacore suffers really badly. Neither autonuma or
balancenuma do great. The reasons why balancenuma suffers have already
been explained -- the scan rate is not reducing but this can be
addressed with a big hammer. A patch already exists that does that but
is not included here.

numacore regresses 63.25% at it's peak and has a 54.10% loss on its
specjbb score.

autonuma regresses 10.01% at its peak, 1.81% on the specjbb score.

balancenuma does "best" in that it regresses the least.

The autonuma file that stored the system CPu usage was truncated for some
reason. I've set it to rerun.

numacores system CPU usage is massive.

balancenumas is also far too high due to it failing to reduce the scan
rate.

So, now I'm seeing compatible figures that have been reported elsewhere.
To get those figures you must use a single JVM, THP must be enabled and it
must run with a large enough number of warehouses. For other configurations
or lower number of warehouses, it can suffer.
